Here is the question / answer. There are three nearly identical answers from three brand new users (Mike, Luds, Ronaldo August Vasquez) over the course of the existence of the question, two of which are from this week (one today). None of the three users has any other activity (so far). It feels like someone is either trying to load or reinforce the answer, or something just happened in the wilds of the internet and my question is getting more attention and a second variant solution, which is entirely possible.
Or, it's 3 new users who don't have access to add comments to a successful answer saying "this worked for me" and instead are posting nearly identical answers copied from each other, but hey why not ask if there is something fishy.
Note that I do accept if there is an alternate or new solution, but something seems odd about what's happening. Any moderator with a couple free minutes feel like confirming/denying my paranoia by comparing/contrasting IPs, or however else it might get done?
Of note, I've already flagged today's answer as a duplicate of the one from 2 days ago because it was, so if it's missing you'll have to roll back. Sorry for the potential inconvenience.
